“Our approach to North Korea is to have them change their posture towards any future talks,” Tillerson said in an interview with NPR aired Friday. “We do not seek a collapse of the regime. We do not seek an accelerated reunification of the peninsula. We seek a denuclearized Korean peninsula.”

“North Korea has to decide they’re ready to talk to us about the right agenda — and the right agenda is not simply stopping where they are for a few more months or a few more years and then resuming things. That’s been the agenda for the last 20 years,” Tillerson said.
